EX-IM BANK OFFICIALS FACE INVESTIGATIONS: The U.S. Export-Import Bank has suspended or removed four officials in recent months amid investigations into allegations of gifts and kickbacks, as well as attempts to steer federal contracts to favored companies. One employee allegedly accepted cash in exchange for trying to help a Florida company obtain U.S. government financing to export construction equipment to Latin America. Two others are being investigated over allegations of improperly awarding contracts to help run the agency, and a third is being investigated over allegations of accepting gifts on behalf of a company seeking financing.

The Ex-Im Bank hasn’t disclosed information about the investigations, which come at a pivotal time for the 80-year-old agency as Congress considers whether to reauthorize it. Two of the top three House Republican leaders now say they won’t agree to authorize the agency’s charter after it expires in September. Allegations of misconduct could complicate the already difficult political environment for those who do support the agency. Damian Paletta reports.
